Roofing in Sedro-Woolley
What foothill weather does to a Sedro-Woolley roof.
Storms coming up the Skagit River drop more rain here than in Mount Vernon or Burlington, and tall firs keep many roofs shaded and damp.
Sedro-Woolley homes
From downtown classics to homes in the trees.
Many older homes near downtown Sedro-Woolley have layers of past roofing, cedar boards underneath, or decking that has been patched over the years. We tear off to the deck, replace anything soft, and give you a clean, watertight roof.
Out toward the river and up into the hills, homes sit under heavy tree cover. We pay close attention to ventilation, valleys and gutters so those roofs can dry out between storms.

What's included
Every Topside roof replacement includes:
Full tear-off to the deck
No roofing over old roofing. We remove everything so the deck can be checked.
Decking repair
Soft or rotted plywood is replaced before the new roof goes on.
Underlayment and leak barrier
Synthetic underlayment, plus ice and water leak barrier in valleys and at eaves.
New flashing
Walls, chimneys, skylights and vents get new flashing, not reused metal.
Ventilation check
Ridge and intake venting sized so the attic can dry out in our damp months.
Cleanup and walkthrough
Magnet sweep for nails, all debris hauled away, and a final review with you.

Sedro-Woolley roofing questions
Do you serve all of Sedro-Woolley?
Yes. Topside works across Sedro-Woolley and eastern Skagit County, including Lyman, Hamilton, Clear Lake and Big Lake.
Do you do roof repairs too, or only replacements?
Both. If the roof is in good shape and the problem is in one area, a repair may be all you need. See our roof repair page.
How much does a new roof cost in Sedro-Woolley?
It depends on roof size, pitch, layers, material and what we find under the old roof. We give a free written estimate, and monthly payments are available through our financing partners.
What about moss on my roof?
Moss holds water against the shingles and lifts their edges. We can clean and treat a roof that still has life left, or talk through replacement if the shingles are worn out. See roof maintenance.
Is Topside local?
Yes. Topside is a family-owned roofing company based in Bellingham that has served Skagit County since 1989.
